CROSS REFERENCE TO RELATED APPLICATIONS This application claims priority to US patent application No. 14 / 801,118, filed July 16, 2015, and US provisional application number 62, filed July 16, 2014. Also claims the benefit of / 025,271. The entire disclosure of the above application is incorporated herein.

  The present disclosure generally relates to anchor bolts. By way of example and not limitation, anchor bolts are widely used in the construction industry to secure structural members to a concrete foundation, with at least a portion of the anchor bolt being embedded in the concrete foundation.

  This section presents background information related to the present disclosure that is not necessarily prior art.

  In the construction industry, anchor bolts are well-known devices that are widely used to secure building structures such as walls to concrete foundations. Conventionally, anchor bolts are made of steel rods and have an “L” shape. This “L” -shaped horizontally extending base is commonly referred to as the anchor bolt tail, and the “L” vertically extending portion is generally referred to as the anchor bolt shank. A male screw is provided at the end of the shank located on the opposite side of the tail, and a nut is fitted. Anchor bolts are usually placed before the concrete foundation is poured or set in the concrete foundation while the concrete is wet (ie after the concrete foundation is poured and before the concrete foundation hardens) . In either case, the anchor bolt is temporarily held in place by a mounting plate that is secured to the concrete foundation template while the concrete foundation is cured. Alternatively, the anchor bolt is held in place by an anchor bolt float that rests on the concrete foundation while the concrete foundation hardens. Once the concrete foundation has hardened, these template, mounting plate and / or anchor bolt float are removed and discarded, leaving the threaded ends of the anchor bolts protruding from the concrete foundation. Thereafter, holes aligned with the threaded ends of these anchor bolts are drilled into one or more structural members of the wall. Furthermore, the structural member of the wall is arranged on the anchor bolt so that the threaded end of the anchor bolt extends through the hole. Further, the nut is screwed into the threaded end of the anchor bolt, and the nut is fastened to the structural member of the wall, thereby completing the installation process.

  The conventional anchor bolt has a safety problem before the structural member of the wall is placed on the anchor bolt because the threaded end of the anchor bolt protrudes from the mounting surface of the concrete foundation. Thus, construction workers and people walking on other concrete foundations could be injured, such as by tripping over the threaded end of the anchor bolt. In addition, conventional anchor bolts have various sizes and shapes depending on the application. The contractor must consider these various available anchor bolts and select the type of anchor bolt that would be appropriate for the particular concrete foundation to be placed. If an inappropriate anchor bolt is selected or the concrete foundation is changed during work, another type of anchor bolt must be ordered, resulting in work delays and inconveniences. This is particularly troublesome as the concrete filling schedule must be readjusted and other work premised on the finished concrete foundation may be delayed. Therefore, there is a demand for an anchor bolt device that is safer and has excellent adaptability at the work site.

  This section presents a general summary of the disclosure and is not a comprehensive disclosure of its entire scope or all features.

  According to one aspect of the present disclosure, an anchor bolt device for fixing a structural member to a concrete foundation is described. The anchor bolt device includes a first anchor bolt. The first anchor bolt extends between the first end and the second end, and includes an enlarged diameter portion, a shank portion, and a tail portion. The enlarged diameter portion of the first anchor bolt extends from the first end portion of the first anchor bolt along the enlarged diameter portion center line. The enlarged diameter portion of the first anchor bolt has an enlarged diameter section that crosses the enlarged diameter center line of the first anchor bolt. The tail portion of the first anchor bolt extends from the second end portion of the first anchor bolt along the tail portion center line. The tail portion of the first anchor bolt has a tail section crossing the tail center line of the first anchor bolt. The shank part of the first anchor bolt is provided between the enlarged diameter part and the tail part of the first anchor bolt and extends along the center line of the shank part. The shank portion of the first anchor bolt has a shank portion cross section that crosses the shank portion center line of the first anchor bolt. The cross section of the shank portion is smaller than the cross section of the enlarged diameter portion. A first coupling for fixing the first anchor bolt to the structural member is provided at the first end of the first anchor bolt. The first coupling has a female thread portion extending inwardly from the first end portion of the first anchor bolt to the enlarged diameter portion of the first anchor bolt.

  According to another aspect of the present disclosure, the anchor bolt device includes a first anchor bolt and a second anchor bolt. The second anchor bolt is connected to the first anchor bolt and extends from the first anchor bolt. Each of the first and second anchor bolts extends between the first end portion and the second end portion, and includes an enlarged diameter portion, a shank portion, and a tail portion. The enlarged diameter portions of the first and second anchor bolts extend along the enlarged diameter portion center line from the first end portions of the first and second anchor bolts, respectively. The enlarged diameter portions of the first and second anchor bolts have an enlarged diameter section crossing the enlarged diameter center line. The tail portions of the first and second anchor bolts extend along the tail center line from the second ends of the first and second anchor bolts, respectively. The tail portions of the first and second anchor bolts have a tail section that crosses the tail centerline. The shank portions of the first and second anchor bolts are provided between the enlarged diameter portion and the tail portion of the first and second anchor bolts, respectively, and extend along the center line of the shank portion. The shank portions of the first and second anchor bolts have a shank portion cross section that crosses the shank portion center line. The shank part cross section of the first and second anchor bolts is smaller than the cross section of the enlarged diameter part of the first and second anchor bolts. A first coupling is provided at a first end of the first anchor bolt to secure the first anchor bolt to the structural member, and a second coupling connects the first and second anchor bolts to the second Provided at the first end of the anchor bolt. The second coupling houses at least a portion of the tail portion of the first anchor bolt and connects the first anchor bolt to the second anchor bolt.

  As a result, the anchor bolt devices described herein exhibit numerous advantages and overcome the problems of conventional anchor bolts. First, it is possible to embed the first anchor bolt deeper in the concrete foundation by the female thread portion of the first coupling disclosed in the present specification. Unlike the external thread found in conventional anchor bolts, the internal thread portion of the first coupling described herein needs to protrude from the concrete foundation to secure the structural member to the first anchor bolt and thus to the concrete foundation. There is no. Therefore, it is possible to install the first end of the first anchor bolt flush with the mounting surface of the concrete foundation. Thereby, it is possible to provide a safer work site in which it is not necessary for the construction worker and other personnel to get into the screw end portion of the anchor bolt exposed from the concrete foundation or to be injured. Secondly, the structure of the second coupling described herein enables a plurality of anchor bolts to be connected quickly and easily. As a result, it is possible to create a custom-designed anchor bolt device that satisfies the requirements of the concrete foundation and construction structure that the construction worker is working on site. This provides greater field adaptability and is described above with respect to errors in the initial selection of anchor bolts and / or that the anchor bolts must be reordered due to field changes to the concrete foundation. Problems are reduced and / or eliminated.

  The first anchor bolt 26 of the anchor bolt device 20 will be described with reference to FIGS. 1 and 2. The first anchor bolt 26 extends between the first end portion 28 and the second end portion 30. The first anchor bolt 26 generally includes an enlarged diameter portion 32, a shank portion 34, and a tail portion 36. The enlarged diameter portion 32 of the first anchor bolt 26 extends from the first end portion 28 of the first anchor bolt 26 along the enlarged diameter portion center line 38. The tail portion 36 of the first anchor bolt 26 extends along the tail portion center line 40 from the second end 30 of the first anchor bolt 26. The shank portion 34 of the first anchor bolt 26 is provided between the enlarged diameter portion 32 and the tail portion 36 of the first anchor bolt 26 and extends along the shank portion center line 42. As shown in FIGS. 1 and 2, the enlarged-diameter portion center line 38, the shank portion center line 42, and the tail portion center line 40 of the first anchor bolt 26 may be linear. Regardless of the above, the diameter-enlarged portion center line 38, the shank portion center line 42, and the tail portion center line 40 of the first anchor bolt 26 may be non-linear. As a non-limiting example, the enlarged diameter center line 38, the shank center line 42, and the tail center line 40 of the first anchor bolt 26 may be curved (not shown).

  The enlarged diameter portion 32 of the first anchor bolt 26 has an outer surface 44 located between the first end portion 28 of the first anchor bolt 26 and the shank portion 34 of the first anchor bolt 26. The enlarged diameter portion 32 of the first anchor bolt 26 has an enlarged diameter section 46 that crosses the enlarged diameter center line 38 of the first anchor bolt 26. The enlarged diameter section 46 of the first anchor bolt 26 may be formed so as to be surrounded (ie, partitioned) by the outer surface 44 of the enlarged diameter section 32 of the first anchor bolt 26. The tail portion 36 of the first anchor bolt 26 has an outer surface 48 located between the second end 30 of the first anchor bolt 26 and the shank portion 34 of the first anchor bolt 26. The tail portion 36 of the first anchor bolt 26 has a tail section 50 that crosses the tail centerline 40 of the first anchor bolt 26. The tail section 50 of the first anchor bolt 26 may be generally formed as being surrounded (ie, partitioned) by the outer surface 48 of the tail section 36 of the first anchor bolt 26. The shank portion 34 of the first anchor bolt 26 has an outer surface 52 provided between the enlarged diameter portion 32 of the first anchor bolt 26 and the tail portion 36 of the first anchor bolt 26. The shank portion 34 of the first anchor bolt 26 also has a shank portion cross section 54 that crosses the shank portion center line 42 of the first anchor bolt 26. The shank portion cross section 54 of the first anchor bolt 26 may be generally formed as being surrounded (ie, partitioned) by the outer surface 52 of the shank portion 34 of the first anchor bolt 26. The shank portion cross section 54 of the first anchor bolt 26 is smaller than the expanded diameter cross section 46 of the first anchor bolt 26. On the other hand, the size of the tail portion cross section 50 of the first anchor bolt 26 relative to the shank portion cross section 54 of the first anchor bolt 26 can be changed. For example, in the configuration shown in FIGS. 1 and 2, the tail section 50 of the first anchor bolt 26 is equal in size to the shank section 54 of the first anchor bolt 26. Alternatively, the tail section 50 of the first anchor bolt 26 may be smaller or larger than the shank section 54 of the first anchor bolt 26. In the structure shown in FIGS. 1 and 2, the enlarged diameter section 46, the tail section 50, and the shank section 54 of the first anchor bolt 26 are all circular. Therefore, the outer surface 44 of the enlarged diameter portion 32 of the first anchor bolt 26, the outer surface 48 of the tail portion 36 of the first anchor bolt 26, and the outer surface 52 of the shank portion 34 of the first anchor bolt 26 are all cylindrical. Of course, other shapes may be employed without departing from the scope of the present disclosure (FIGS. 6 to 9).

  With continued reference to FIGS. 1 and 2, the first anchor bolt 26 has a bent portion 56 provided between the shank portion 34 and the tail portion 36 of the first anchor bolt 26. In the bent portion 56 of the first anchor bolt 26, the shank portion center line 42 and the tail portion center line 40 of the first anchor bolt 26 intersect each other at a first angle 58. The first angle 58 may be in the range of 85 degrees to 95 degrees. As a non-limiting example, in FIGS. 1 and 2, the first angle 58 is shown as 90 degrees. As shown in FIGS. 1 and 2, the enlarged diameter center line 38 and the shank portion center line 42 of the first anchor bolt 26 are arranged coaxially. In addition, the first anchor bolt 26 has a transition portion 60 disposed between the enlarged diameter portion 32 and the shank portion 34. The cross section of the transition portion 60 of the first anchor bolt 26 is gradually tapered as it moves from the enlarged diameter portion 32 of the first anchor bolt 26 to the shank portion 34 of the first anchor bolt 26. Accordingly, the transition portion 60 of the first anchor bolt 26 shown in FIGS. 1 and 2 has a frustum shape. However, the transition portion 60 of the first anchor bolt 26 may have a different shape. As a non-limiting example, the transition portion 60 of the first anchor bolt 26 may have a step (not shown).

  As further shown in FIG. 3, the first anchor bolt 26 is configured to be at least partially received (ie, buried or submerged) in the concrete foundation 24. The concrete foundation 24 may generally have a mounting surface 62. As an example, the concrete foundation 24 may be leveled during curing, or otherwise finished so that the mounting surface 62 of the concrete foundation 24 is relatively flat. In many cases as shown in FIG. 3, the mounting surface 62 extends in the horizontal direction, whereas the enlarged diameter portion 32 and the shank portion 34 of the first anchor bolt 26 extend in the vertical direction. However, such orientation is for illustrative purposes only and is not intended to be limiting. The first anchor bolt 26 may be disposed in the concrete foundation 24 such that the first end 28 of the first anchor bolt 26 is flush with the mounting surface 62 of the concrete foundation 24. By doing so, most of the first anchor bolt 26 including the shank portion 34, the tail portion 36 and the second end portion 30 of the first anchor bolt 26 is embedded in the concrete foundation 24. Similarly, as shown in FIG. 3, the tail portion 36 includes a second end portion 30 of the first anchor bolt 26, and a tail portion center line 40 and a shank portion center line 42 in the bent portion 56 of the first anchor bolt 26. It has a predetermined length 64 that is measurable along the tail centerline 40 between the intersection points. A first truncated cone 66 is formed in the concrete foundation 24 by a predetermined length 64 of the tail portion 36 of the first anchor bolt 26. The first truncated cone 66 shown in FIG. 3 has a conical shape including the shank portion 34 of the first anchor bolt 26, and extends upward from the tail portion 36 of the first anchor bolt 26. The first truncated cone 66 represents the portion of the concrete foundation 24 that resists removal of the first anchor bolt 26.

  As shown in FIGS. 1 to 5, a first coupling 68 is provided at the first end portion 28 of the first anchor bolt 26. The first coupling 68 is configured to secure the first anchor bolt 26 to the structural members 22, 22 '. Although it is possible for the first coupling 68 to have different structures, all of which are considered within the scope of this disclosure, the first coupling 68 in the illustrated example is the first end of the first anchor bolt 26. An internal thread portion 70 extending from the portion 28 to the inside of the enlarged diameter portion 32 of the first anchor bolt 26 is provided. The internal thread portion 70 of the first anchor bolt 26 may be a hole provided with an internal thread and concentrated (that is, interrupted) in the enlarged diameter portion 32 of the first anchor bolt 26. As shown in FIGS. 1 and 3, the anchor bolt device 20 may include a screw protection part 72 that covers the female thread part 70 of the first coupling 68. The screw protection portion 72 has a plug portion 74 that is sized to be accommodated in the female screw portion 70 of the first coupling 68. When inserted into the female threaded portion 70 of the first coupling 68, the screw protector 72 causes the female threaded portion 70 of the first coupling 68 to flow from the scattered material during the pouring, leveling and / or finishing operations of the concrete foundation 24. Protect. The screw protection portion 72 may further include a flange portion 76 that extends radially outward from the plug portion 74. The flange portion 76 of the screw protection portion 72 contacts the first end portion 28 of the first anchor bolt 26 when the plug portion 74 of the screw protection portion 72 is accommodated in the female screw portion 70 of the first coupling 68.

  As shown in FIGS. 4 and 5, the anchor bolt device 20 further includes a fastener 78 having a head 80 and a shaft portion 82. The shaft portion 82 of the fastener 78 is provided with a male screw and can be inserted into the female screw portion 70 of the first coupling 68. Therefore, the shaft portion 82 of the fastener 78 can be screwed into the female screw portion 70 of the first coupling 68 and held. Thus, this fastener 78 can be used to connect the first anchor bolt 26 to the structural members 22, 22 '. As shown in FIGS. 4 and 5, the structural members 22, 22 ′ may be disposed on the mounting surface 62 of the concrete foundation 24 and may have an opening 84 therein. The one or more openings 84 are sized to completely penetrate the structural member 22 and accommodate the shaft 82 of the fastener 78. In use, the shaft portion 82 of the fastener 78 is inserted into one of the openings 84 of the structural member 22 and the female screw portion 70 of the first coupling 68. The head 80 of the fastener 78 is configured to abut against the structural member 22 in the vicinity of the opening 84, so that the shaft portion 82 of the fastener 78 is screwed into the female screw portion 70 of the first coupling 68. Accordingly, the structural member 22 is fixed to the enlarged diameter portion 32 of the first anchor bolt 26.

  As shown in FIG. 4, the structural members 22 and 22 ′ are configured as a template 22. As shown in FIG. 4, the concrete foundation 24 may be fixed using one or more templates 86. By using such a template 86, when the concrete foundation 24 is poured, the flow of the concrete is restricted so that the concrete collects and hardens in an area limited by the template 86, and the size and shape of the concrete foundation 24 are thereby reduced. May be defined. The first anchor bolt 26 may be positioned in the concrete foundation 24 using the template 22. Thus, the template 22 may be disposed on the mounting surface 62 of the concrete foundation 24 and further supported and fixed by the template 86. The template 22 forms one or more openings 84 sized to accommodate the shaft 82 of the fastener 78. In order to position the first anchor bolt 26 in the concrete foundation 24, the shaft portion 82 of the fastener 78 is inserted through one of the openings 84 provided in the template 22, and the female screw portion 70 of the first coupling 68 is inserted. Threaded onto. When the concrete foundation 24 is cured, the fastener 78 may be removed from the female thread portion 70 of the first coupling 68 and extracted from the opening 84 of the template. The template 22 and the template 86 may then be discarded.

  As shown in FIG. 5, the structural members 22, 22 'are configured as bottom plates 22, 22' of a wall structure (not shown). Illustrating in a non-limiting manner, the bottom plate 22 'may comprise a single plate or a plurality of laminates (such as 2x4, 2x6, 2x8, 2x10, 2x12, 4x4, 6x6, or 8x8 sized lumber). As shown in FIG. 5, the bottom plate 22 ′ is disposed and installed on the mounting surface 62 of the concrete foundation 24. The bottom plate 22 ′ forms one or more openings 84 sized to accommodate the shaft portion 82 of the fastener 78. In order to install the bottom plate 22 ′ on the concrete foundation 24, the shaft portion 82 of the fastener 78 is inserted through one of the openings 84 provided in the bottom plate 22 ′ and screwed into the female screw portion 70 of the first coupling 68. Together, the bottom plate 22 ′ is fixed to the enlarged diameter portion 32 of the first anchor bolt 26. A disc-shaped washer 88 may be disposed between the head 80 of the fastener 78 and the bottom plate 22 '. In this case, the washer 88 extends annularly around the shaft portion 82 of the fastener 78 to help prevent the head 80 of the fastener 78 from passing through the bottom plate 22 'of the wall structure. Regardless of the embodiment shown and described herein, the structural members 22, 22 'need not be a wall template 22 or a bottom plate 22'. In addition, the structural members 22, 22 'may be of various different shapes and sizes, and may be made of wood or other materials such as, but not limited to, various metals.

  As described above, the first anchor bolt 26 has a circular shape, but the first anchor bolt 26 has different shapes, although the structure of the enlarged diameter section 46, the tail section 50, and the shank section 54 is circular. It can be configured as follows. Furthermore, the enlarged diameter section 46, the tail section 50, and the shank section 54 of the first anchor bolt 26 may all have the same shape or different shapes, and various combinations are possible. is there. For example, in FIGS. 6 to 9, the enlarged diameter section 46 and / or the shank section 54 of the first anchor bolt 26 has at least one flat surface 90. More specifically, each of the enlarged diameter section 46 and the shank section 54 of the first anchor bolt 26 in FIGS. 6 and 7 has a total of four flat surfaces 90 and has a rectangular shape. On the other hand, the tail section 50 has a circular shape. In another embodiment shown in FIGS. 8 and 9, the enlarged diameter section 46 of the first anchor bolt 26 has a total of six flat surfaces 90 and is hexagonal in shape. According to this structure, both the tail part cross section 50 and the shank part cross section 54 are circular. The flat surface 90 resists rotation of the first anchor bolt 26 in the concrete foundation 24, thereby forming a stronger mechanical connection between the first anchor bolt 26 and the concrete foundation 24. Another configuration is shown in FIG. In FIG. 10, the tail section 50 and the shank section 54 have a circular shape, and the outer surface 52 of the shank section 34 of the first anchor bolt 26 extends spirally along the shank section 34 of the first anchor bolt 26. One or more twist flats 92 are provided. This alternative configuration is advantageous in that the torsion flat 92 provides resistance to the first anchor bolt 26 being pulled from the concrete foundation 24.

  Another embodiment of the anchor bolt device 20 is shown in FIGS. Among these, the anchor bolt device 20 includes a second coupling 94 provided at the second end 30 of the first anchor bolt 26. A first locking member 96 is connected to the second end 30 of the first anchor bolt 26 by a second coupling 94. The first locking member 96 extends outward from the outer surface 48 of the tail portion 36 of the first anchor bolt 26 to form a first truncated cone 66 in the concrete foundation 24 (see FIG. 3).
